SCREEN-DOOR.

To all whom t may concern.'

Be it known that I, MARY BOWERS., a citizen of the United States, residing at Angora, in the county of Morrill and State of Nebraska, have invented new and useful lm-l provements in Screen-Doors, of which the following is a specification.

rlhis invention relates to screen doors; and it has for its object the provision of a structure of this. character which may be constructed wholly of metal whereby it will be positive-ly held against warping incident to its exposure to the weather.

A further object of the invention is to provide means for facilitating the attachment of the foraminous material or screen cloth over the opening of the frame and for positively preventing the accidental disconnection of the cloth from the frame.

l/Vith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

ln the accompanying drawings :#Figure 1 is a perspective view of the frame with the cloth thereof removed; Fig. 2 is a similar view, showing the cloth applied; and Fig. 3 is a section on line 3--3 of Fig. 2. Fig. Il is a lhorizontal section, taken through a portion of the screen, showing a slightly modified form of the invention.

The door comprises'parallel vertical side bars 1, which are preferably constructed of thin metal having intermediate longitudinally stamped portions presenting continuous concavities 2 for a purpose to be hereinafter described. The said concavities 2 are of a restricted diameter toward their open ends, as illustrated in Fig. 3. The transverse connecting strips 3 are also constructed of metal and are substantially identical with the vertical bars 1. The extremities of the strips 3 are offset at 4 and provided with short attaching flanges 5, which Aare secured in any suitable well known manner to the inner flanges 6 of the bars 1. ln this manner the cloth attaching surfaces of the strips 3 come flush with the cloth attaching surfaces of the vertical bars 1. The strips 3 are provided with longitudinal concavities 7, which are identical with the concavities 2, being disposed at right angles with relation thereto and terminating immediately adjacent the inner edges of the flanges 6 of the vertical bars 1.

Specification of Letters lPatent.

Application filed January 8, 1913.

Patented Nov. 1.1 1913.,

Serial No. 740,847.

The foraminous cloth 8 is extended env tirely overthe opening provided by the bars 1 and 3 of the door, while the marginal edges of said cloth are extended over the bars and then bent into the concavities 2 and 7 therein, as at 9. Beading strips 1() are compressed in the concavities 2 and 7 against the marginal edges of the cloth 8, clearly shown in Fig. 3, sufficient pressure being applied against the strips whereby they are wholly expanded or brought int-o contact with the walls of the concavities to be thereby held against accidentally escaping therefrom. As stated the concavities 7 terminate immediately adjacent the inner vertical edges of the vertical bars 1. In view thereof the concavities of one strip are arranged wholly out of registration with the concavities of the adjacent strip. lVith a View to completely sealing the joints between the cloth 8 and the respective bars 1 and 3 at the vcorners of the door frame, I provide metallic attaching plates 11, which are secured to the strips 1 by screws 12 or equivalent fastening devices. Suitable braces 13 connect the vertical bars 1 with the bottom strip 3 so as to maximize the rigidity of the structure and prevent the same from bend-V ing.

New that the details of construction are clearly described, it is evident that the strips 10 may be conveniently removed when it is desired to substitute a new screen cloth 8 for a worn cloth; that the strips 1() form efficient fastening elements for holding the cloth operatively associated with the respective elements of the door frame and that the structure as a whole is one which may be eX- posed to the weather without being distorted or buckled.

ln the modified form of the invention shown in Fig. ll, each side bar 10a of the structure support-s a laterally extensible bar ,10b having one or more elongated slots 10c which receive clamping bolts 10l of the bar 10a. From this construction, it is evident that the structure may be .extended laterally to accommodate itself to doorways of different sizes.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the mino-r details of construction may be resortedto Without departing from the principle or sacrificing any of the advantages of this invention, as claimed.

Having thus described my invention, whatv I claim is:

A screen door comprising a frame including identical side bars grooved throughout their length and each having inwardly eX- tending anges, end bars interposed between the side bars and having their ends overlying the fianges of the side bars, the said end bars having grooves formed therein and arranged longitudinally thereof and terminating within the anges of the side bars, a single strip of oraminous material overlying the frame and having portions extending into the grooves of the side and end bars, fastening strips embedded in the grooves in the side and end bars9 and adapted to secure the said material therein,V and corner plates overlying the side and end bars and secured thereto, whereby to confine the strips in the grooves and also to seal the joints between the cloth and the respective side and end bars.

In testimony whereof I atflx my signature in presence of two witnesses.
